Since having a baby, I've suddenly found myself more inclined to cook family meals each night, keep the kitchen clean and hunt like crazy for deals at the grocery store (also part of staying on our budget!). One site that has helped keep me focused on preparing healthy meals for a low price is $5 Dinners. Erin posts daily recipes she makes for her family for less than $5 per meal, and I can tell you from trying many of these recipes myself - they're GREAT!
She just had a cookbook published and is doing a HUGE giveaway over at her site. Even if you don't win the cookbook, peruse the site. You'd be surprised at the inspiration you find there!
